Predictors and short-term outcomes of post-stroke fatigue in initial phase of transition from hospital to home: A prospective observational study. [PDF]
Abstract Aim To analyse the interactions of associated factors with post stroke fatigue (PSF) after discharge home and determine the predictors of PSF and their impact on stroke survivors. Design A prospective observational study. Methods A total of 94 patients with acute stroke were recruited between May 2019 ‐July 2020. The main outcomes were fatigue,

Background. Fatigue is one of the most common symptoms among breast cancer survivors. Although massage therapy has been commonly used for fatigue management, relevant evidence on the effectiveness of massage therapy for the reduction of fatigue in breast cancer survivors is still unclear. Objective.

Abstract Survivors of traumatic events commonly suffer from long‐term pain and related somatic symptomatology. To test the predominant hypothesis that survivors’ pain comprises sequela of persistent posttraumatic stress symptoms (PTSS), we assessed the sequential order of symptom development among young survivors of a terrorist attack.

针对钢桥中钢板疲劳裂纹进行了一系列疲劳裂纹修复试验研究,以确定不同修复方法下结构的疲劳性能。高弹模CFRP(碳纤维增强复合材料)修复法是通过粘贴高弹模CFRP布来增大结构刚度,以延长结构疲劳寿命,且碳纤维材料基本不会产生疲劳裂纹,具有较好的抗疲劳效果。采用数值模拟和试验研究相结合的方法,首先对修复钢板的应力分布和特点进行了详细的分析,然后通过3组对比疲劳试验,确定了不同修复方法对损伤钢板疲劳寿命的增强效果。最后利用修复试验值与各国规范规定的S-N曲线进行比较,分析已修复钢板的疲劳性能。研究结果表明 ...

风电机组大型化逐渐成为我国中东部、南部等低风速区风电塔的发展趋势。单机容量大型化带来的机头极限荷载和疲劳荷载的提升,给传统风电单管式钢塔筒支撑结构的设计、制造和运输带来了巨大挑战。为解决此问题,提出了一种构架式预应力抗疲劳钢管风电塔,在降低支撑结构用钢量、提升结构刚度避免共振的同时,通过在塔柱钢管内张拉预应力钢绞线的方式,降低塔柱焊接节点所受疲劳外荷载应力幅的平均应力,从而延长其疲劳寿命,并改善疲劳脆性破坏特性。基于上述预应力抗疲劳构架塔概念,通过整理总结相关规范和标准的规定以及文献研究结论 ...

ABSTRACT Laser powder bed fusion (LPBF) of Inconel 718 alloy inevitably introduces pronounced microstructural anisotropy, typified by columnar grains and robust crystallographic texture. This results in direction‐dependent fatigue behavior, raising critical reliability concerns for high‐stakes aerospace applications.
